No way. Hounding users on an internet site can cause a lot of annoyance and status problems, but it's not creepy, i.e. it entails no shared threat of bodily harm.

I disagree with your definition of "creepy". However, whether we define the word that way or not, would you agree that it is behaviour worth discouraging?

It is one thing to disagree with a view that someone is expressing. It is quite another to follow that person around, disproportionately, in order to find opportunities to disagree specifically with them, (whether that's in order to make them feel unwelcome and drive them out, or whether via some twisted logic the hounder feels it gains them dominance or even sees it as courting behaviour).
